Slit lamp is a medical device usable in diagnose the problems related to human eye. It is an instrument consisting of a high-intensity light source that can be focused to shine a thin slit of light into the eye.
The binocular slit-lamp examination provides a stereoscopic magnified view of the eye structures in detail, enabling anatomical diagnoses to be made for a variety of eye conditions.
Currently available slit lamps are too big and very expensive. They have a very complex structure. There are some portable ones also available but they are also very expensive.
We are making a
portable slit lamp which whole design can be 3D printed. It have very less
components and it is very light weight also.

3D Printable Portable Slit Lamp:
The design is so that it facilitates portability to the user. With minimum number and very fundamentally designed components, this can be taken along/printed at your desired place. It also makes it really cost effective and affordable to almost each section of the society in need, specially those who can not afford large expenditures on initial identification of the problems.
It comprises of :
